Adams Rite 4900-36-101-628 4900 Heavy Duty Deadlatch, Standard Faceplate, 1-1/8" Backset, RH or LHR Handling for Flat 4-5/8" Mortised Strike, Clear Anodized

Deliver reliable access and flexible traffic control with the Adams Rite by ASSA ABLOY 4900 Heavy Duty Electrified Deadlatch. Designed for commercial entrances where secure monitoring and smooth egress are critical, this electrified deadlatch gives facility managers a dependable way to control two‑way or exit‑only traffic through a simple, key‑controlled bolt hold‑back. Built from stainless steel with a clear anodized finish, the 4900 withstands heavy use while resisting corrosion for long life.

The 4900 installs into standard mortised preparations and accommodates a 1-1/8 in backset and a flat 4-5/8 in mortised strike, making it an ideal retrofit choice for MS1850S, 4510 and discontinued 4700 cutouts—saving installation time and reducing modification costs. Handing is field‑reversible (RH or LHR) with only a screwdriver, and the auxiliary stainless steel latchpin prevents common forced‑entry techniques, enhancing perimeter security and integration with access control, surveillance, and monitoring systems.
